Symphony in D Minor’ is a kinetic sculpture that reacts to people below it to create an audio visual thunderstorm in hanging resin sculptures. The sculpture is a collaboration between Patrick Gallagher and Chris Klapper.

According to the creators, “the viewer can compose a cacophony of sound using variations of thunder, wind, rain and lightning or choose to hear the subtle breeze of an isolated wind far away.” The sculpture’s form is inspired by the arcus cloud, which is a low, horizontal, and cylindrical-shaped cloud formation.
